3COM® BASELINE SWITCH 2900 PLUS FAMILY KEY BENEFITS (CONTINUED) NO SWITCH SETUP REQUIRED Baseline Plus switches are operational straight out-of-the-box; as long as default settings are acceptable, there is no need to configure the switch. If desired, the switch can be configured using a web browser, console port, or SNMP management software. ENHANCED INTUITIVE MANAGEMENT OPTIONS For networks that require more control, the switch web management interface provides an intuitive, menudriven process for even novice users to quickly and confidently configure the switch during initial setup and manage it during normal operation. Graphical switch and port views provide a clear understanding of switch status and configuration. In addition, the web interface features individual port-traffic monitoring (port mirroring) and MAC address port mapping tables. A cable diagnostic tool lets users troubleshoot basic connectivity problems via the web management interface further simplifying network installation. The Baseline Switch 2900 family is also supported by 3Com Network Supervisor (3NS) and 3Com Network Director (3ND) management software. 3NS and 3ND can be used to map the network topology, indicating what devices are connected, and on what ports. Switch management and software upgrades can be easily done. Other SNMP-based management tools may also be used. The Switch family also supports a compact Command Line Interface (CLI) that is accessed via the front panel console port. Using the CLI, major switch management options can be quickly configured. FEATURES HIGHLIGHTS Feature Performance VLANs Description Segment the network by grouping users based on their data or traffic exchange requirements. This ensures optimal use of available bandwidth as traffic flow is directed according to the needs of the business. Advanced QoS and traffic shaping Traffic prioritization, using IEEE 802.1p Quality of Service (QoS) and Type of Service (TOS) with Differentiated Services Code Point (DSCP), and ingress/egress rate shaping help ensure that critical time-sensitive traffic like voice gets the priority needed for quality communications. Link aggregation (trunking) Group together any number of ports automatically using Link Aggregation Control Protocol (LACP), or manually, to form an ultra-high-bandwidth connection to the network backbone; help prevent traffic bottlenecks. Rapid Spanning Tree Protocol support Improves network compatibility, scalability and availability. IGMP snooping Multicast filtering optimizes network performance, instead of flooding traffic to all ports. Unique voice features Automatic assignment of voice traffic to separate VLANs ("auto-voice VLAN"), advanced voice QoS, traffic shaping, multicast filtering and PoE support delivers the support necessary for quality voice communications. Flexible Gigabit uplinks Daisychain multiple units together via the built-in copper Gigabit uplink ports or connect to a network backbone via SFP-based fiber modules. PoE support (PWR model only) Provides power for IP phones, wireless LAN access points, and other IEEE 802.3af-compliant devices over the same cable used for data; lowers total cost of ownership since there is no need to run additional electrical wiring. Security IEEE 802.1X network access control Provides standards-based security combined with local authentication. Advanced Access Control Lists (ACLs) MAC- and IP-based ACLs enable network traffic filtering and enhance network control. Traffic monitoring (port mirroring) Administrators can examine suspect data streams received on any port by mirroring the data stream to a monitoring port. Configuration and management Enhanced browser-based interface SNMP support PoE configuration Cable diagnostics Graphical user interface allows even the most novice users to configure the switch during initial setup and monitor it during normal operation. Switch can be managed with 3Com Network Supervisor, Network Director and other SNMP-compatible tools. PoE power can be enabled or disabled per unit and per port; power can also be limited per port. Remotely detect copper cable issues using a browser-based tool. 2
